The study will develop, implement and evaluate a system which provides feedback to physicians regarding patient outcome as it correlates with prior clinical judgments. The study will utilize an automated interactive data system including CRT terminals on-site in the clinic. Three main hypotheses will be tested: 1) information on patient outcome and prior clinical judgments can be collected and meaningfully fed back to the physician, 2) feedback will improve subsequent clinical judgment, 3) feedback will improve patient outcomes. The design phase of the study will include: identification of clinical problem areas and physician subjects, specification of clinical judgments to be followed, determination of patient data to be collected and definitions of parameters for follow-up of patient outcome, design of data files, development of feedback formats which are most understandable and palatable to physicians. Impact of the system will be evaluated through physician assessment of utility of the system, determination of improvement in clinical judgments over time, and measure of change in patient outcomes. Three types of feedback to physicians will occur: calibration feedback (improvement in accuracy of clinical predictions), base rate feedback (rates for specified patient outcomes), and old case review feedback.
